We then carried out a KEGG/GSEA functional enrichment analysis of DEGs between M1 and M0, enriching significant biological functions including Epstein-Barr virus infection, Kaposi sarcoma-associated herpesvirus infection, Ribosome, TNF signaling pathway, and Proteasome (Figure 4(B)). The gene discussed is TNF; the disease is Epstein-Barr virus infection.
